To all whom it may concern:

Be it known that I, ALBERT IV. OBERLIES, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Antifreezing Flush-Tanks, of which the following is a specification.

My invention relates to a new and useful improvement in flush tanks for closets, and has for its object to so construct such a tank and the mechanism therefor as to leave the tank empty when the closet is out of use, thus preventing the possibility of it becoming inoperative through water freezing therein.

#Vith these ends in view, my invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawings, in

which- Figure 1, is a view partly in section and partly in elevation illustrating the invention. Fig. 2, a similar view showing the position of the mechanism when the closet is in use.

A represents the tank which may be of any ordinary construction or material having a valve seat B located in the bottom thereof, and toward which the bottom of the tank is inclined so as to cause the water to readily flow therefrom, and C is the flush pipe leading from the tank to the closet D.

is a stand valve the lower end of which is beveled as indicated at F, so as to fit within the seat B, and when so seated prevent the outfiow of water from the tank, as will be readily understood.

G are fingers for guiding the valve to its seat and thus preventing it from becoming displaced.

The upper end of the stand valve E has attached thereto the yoke H which terminates in an upwardly projecting stem I, upon which is secured the nut J which latter serves as means for the lever K to lift the valve, as shown in Fig. 1. The lever K is pivoted at L and at its opposite end is attached the rod M which passes downward through the tube N and out through the bottom of the tank. This rod and the ball 0 upon the outer end of the lever K should be of sufficient weight to overbalance the valve E and normally hold it in the suspended position shown in Fig. 1, which will permit the contents of the tank to flow therefrom through the flush pipe C, thus normally leaving the tank empty.

P represents the hinged seat which has extending rearward therefrom, the lift bar Q carrying the weight R, which is sufficient to over balance the seat and normally hold it in the elevated position shown in Fig. 1. hen the seat is depressed the bar Q coming in contact with the lower end of the rod M will force the latter upward, which in turn will carry the lever K to the position shown in Fig. 2, thus permitting the valve E to be seated by its own weight. This de pression of the seat will also force the stem S downward and through suitable connections turn on the water which will flow upward through the pipe T and into the tank and so long as the seat is depressed the valve E remaining closed, the water admitted to the tank will be retained therein gradually filling the same, but upon releasing the seat, the weight It will elevate the same, thus freeing the rod M and causing the mechanism of the tank to resume the position shown in Fig. 1, in which the valve is raised from its seat, thus permitting all the water in the tank to flow through the flush pipe to the closet.

WVhile my improvement is adapted for use in connection with all styles of closets, it is especially adapted for use in what are known as outdoor closets, since the latter are exposed to low temperatures in certain seasons of the year and any water left in the tank would be quickly frozen, thus putting the closet out of use.

Having thus fully described my invention, what I claim as new and useful is In combination with a tank having a beveled valve seat in its bottom, a stand valve having an enlarged bottom beveled on its peripheral edge to engage said valve seat, a yoke secured to the top of said valve provided with an upwardly projecting threaded stem, a nut on said stem, a horizontal pivoted lever in said tank having its ends disposed between the ends of the tank, one end of said lever having an opening therein through which said threaded stem passes so as to be engaged by said nut, a tube stationarily sup- In testimony whereof, I hereunto affix ported in said tank and providing at its top my signature in the presence of two subscribend a stop to engage and limit the downward ing Witnesses. movement of the lever, a Weight on the op- ALBERT V.
